有限水深环境中圆柱与圆柱基座之间激振力的研究
, PP. 22-28
Keywords: 衍射,有限深度,虚拟边界,激振力,能量装置
Abstract:
考虑两个同轴的竖直圆柱体,其中一个是实心基座,作为沉箱的近似,另一个是空心圆柱体.这两个圆柱体表现出的衍射现象可以看做是一种波浪能装置.将这些产生的能量转化以后可以得到广泛的实际应用.在各项参数都确定的区域,本文用变量分离的方法得到解析表达式.沿着虚拟边界,通过使用适当的匹配条件,推导和解出了一个含有未知参数的线性系统.由各种可能的解析表达式可得到各个圆柱体的激振力.针对不同的半径和间隙,得到一个激振力的序列.激振力随着半径和间隙的变化而改变.本文用图表的形式描述了这个结果,并进行了对比,最终发现,激振力只有在低频的时候才更加明显.
